Definitions
- the invention relates to a device and a method for filling a container with liquid gas.
- the tank is usually refueled in such a way that the liquid gas is pumped in liquid form from a storage tank into the tank.
- the gas phases of the liquid gas in the container and in the storage tank are simultaneously connected to one another via a separate gas line. In this way, a quantity of gas which corresponds to the volume of the liquid gas supplied to the container reaches the storage tank.
- a disadvantage of this previously known filling method is that if the tank to be filled is contaminated, the gas phase of the storage tank is also contaminated. If other containers are filled from this storage tank, this container may also become contaminated. In addition, during a subsequent refueling of the storage tank, there is also a risk of contamination of the main tank of the liquefied gas production facility.
- the object of the present invention is therefore to provide a possibility for filling containers with liquid gas, in which the contamination of the storage tank is prevented and which is also inexpensive to use.
- the device according to the invention thus has a connection to a storage tank on the one hand and to the container to be filled on the other hand
- Supply line for liquid liquid gas which is provided with a conveyor.
- the conveying device comprises a multi-stage pump or a plurality of pumps connected in series, which build up the pressure required for conveying the liquid gas in several successive pressure stages.
- the container to be filled is provided with a gas discharge line for discharging gaseous liquid gas, which is connected to the supply line for liquid liquid gas at a flow connection.
- a first pump stage of the delivery device between the storage tank and the flow connection of the gas discharge line prevents the inflow of gas from the container into the storage tank.
- a second pump stage of the delivery device arranged in terms of flow between the flow connection of the gas discharge line and the container, at least partially effects the reliquefaction of the gaseous liquid gas supplied.
- the gas phase of the container is therefore not flow-connected to the gas phase of the storage tank. Contamination of the gas phase of the storage tank by the gas phase of the container cannot take place. A control analysis routinely performed on prior art devices prior to filling the storage tank is therefore unnecessary.
- the pressure equalization in the container takes place through an at least partial re-liquefaction of the gas phase flowing out of the container.
- the container to be filled and / or the storage tank is advantageously a mobile tank unit, for example a road tanker, the tank trailer of a road vehicle or a railroad tank car.
- a mobile tank unit for example a road tanker, the tank trailer of a road vehicle or a railroad tank car.
- Carbon dioxide is preferably used as the liquid gas in the device according to the invention.
- the conveying device is designed as a mobile unit which can also be connected to existing storage tanks or containers without any problems.
- the object according to the invention is further achieved by a method having the features of patent claim 6.
- an amount of gaseous liquefied gas, the volume of which essentially corresponds to the volume of the liquid liquefied gas supplied from the storage tank, is removed from the container and liquefied.
- the liquefied gas is returned to the container.
- the pressure built up to transport the liquid liquid gas from the storage tank into the container is expediently used at the same time to liquefy the gaseous liquid gas removed from the container again.
- the pressure for conveying the liquid gas from the storage tank into the container is increased in several pressure stages and the gaseous liquid gas removed from the container is fed between two of the pressure stages. In this way, the inflow of gaseous liquid gas from the container into the storage tank is simply and effectively prevented and an effective liquefaction of the gas removed from the container is achieved.
- Usual operating pressures of customer containers are approx. 17 bar and thus in the same order of magnitude as filling pressures of mobile tank units which are filled with approx. 16 to 20 bar.
- the cooling caused by the pressure reduction when introducing the liquid gas from the tank unit into the container to be filled is not sufficient to during the Filling process to keep the tank pressure reliably below the response pressure of the safety devices.
- the liquid liquefied gas can also be cooled in the storage tank before the filling process. The power consumption required for this is relatively low, since it takes a long time compared to the duration of the filling process.
- the single figure shows a flow diagram of an inventive device for loading and an inventive device for unloading a liquefied gas tanker.
- the storage tank 15 has an outlet 20, by means of which liquid gas can be removed from the storage tank in liquid form.
- a delivery device 21 is connected to the discharge line 20 and has a first pump stage 22 and a second pump stage 23, by means of which the delivery pressure of the delivery device is successively increased to a predetermined delivery pressure can be.
- a gas supply connection 27 is arranged between the first pump stage 22 and the second pump stage 23 and is used for supplying gaseous liquid gas from the tank truck 10 in the manner described in more detail below. In the exemplary embodiment, only two pump stages 22, 23 are shown. However, it is also possible, depending on the requirement for the delivery capacity of the delivery device 21, to provide further pump stages on the feed line 20, both - seen in the flow direction - upstream and downstream of the gas feed line connection 27.
- the delivery device 21 is detachable with the discharge line 20 connected and can for example also be connected in a corresponding manner to an outlet 28 of the tank truck 10.
- a flexible hose line 29 can be connected, which is used to establish a flow connection with the road tanker 10.
- a second hose line 30, which can be connected to the gas supply connection 27, enables a flow connection to the gas phase 13 of the liquid gas located in the tank truck 10.
- the storage tank 15 can be filled in the usual way via a tank feed line 31, the resulting excess gas pressure being able to be compensated for via a gas discharge line 32.
- the filling fittings of the tank truck 10 consist of a liquid gas supply line 35 for supplying liquid liquid gas, which opens into a connecting line 37, a discharge line 28 for removing liquid liquid gas and a gas discharge line 36.
- a conveying device 38 is provided on the discharge line 28, which comprises several pump stages 39, 40 in the same way as the conveying device 21.
- a gas supply connection 41 is arranged between the first pump stage 39 and the second pump stage 40.
- both the conveying device 39 and the liquid gas supply line 35 open into the connecting line 37 the flow paths through the liquid gas feed line 34 and the conveyor 38 are opened or closed as required.
- the liquid gas supply line 35 at the valve 42 is opened and the liquid gas flows into the tank truck 10.
- the liquid gas supply line 35 is led into the interior of the tank truck 10 in such a way that it opens out within the gas phase 13 of the liquid gas present in the tank truck 10.
- the valve 42 is closed and the valve 43 of the discharge line 28 is opened. Liquid gas from the tank truck 10 can now be pumped out by means of the conveyor 38.
- the tanker truck 10 is provided with a connecting head 44, which is used for connecting, for example, the flexible hose line 29.
- the flexible hose line 29 can be connected on the one hand to fill the tank truck 10 with the conveying device 21 on the storage tank 15, and on the other hand can be connected to the storage tank 15 for filling it, as will be described in more detail below.
- the gas discharge line 36 of the tank truck 10 is likewise provided with an end at its end that is fluidically remote from the tank truck 10
- liquid gas is filled into the tank truck 10 by means of the conveying device 21 through the hose line 29 and the connection line 37.
- Gas discharge line 36 derived from the tank truck The derived gas passes through the hose line 30 into the gas supply connection 27 and from there to the pump stage 23 of the delivery device 21.
- the gas withdrawn from the tank truck 10 is liquefied by the pressure change in the pump stage 23 and in liquid form, together with the liquid gas removed from the storage tank 15, the tanker 10 is supplied. After the filling process has been completed, the valve 42 is closed.
- a portion, approximately 25%, of the gas phase existing in the container 45 to be filled must be blown off at an exhaust valve 50.
- the blow-off takes place in a known manner by means of a valve, not shown here, which is flow-connected to the gas phase in the container 45.
- This is particularly useful in order to avoid a gradual accumulation of foreign substances, for example inert or volatile components, which occurs in the course of several filling processes in the course of the filling process.
- Appropriate degassing is recommended by the ISBT (International Society of Beverage Technologists) for containers used in the field of food technology.
- Liquid gas is pumped into the container 45 by means of the pump stages 39, 40 of the delivery device 38.
- the pumped-in liquefied gas displaces the gas present in the container 45, which is supplied to the gas supply connection 41 via the hose line 30 and liquefied in the pump stage 40.
- the gas liquefied in this way is in liquid form together with that from the Tanker truck 10 removed liquid gas fed back to the container 45.
- the gas supplied to the pump stage 40 can be pre-cooled by means of a cooling device 47 integrated in the gas supply connection 41.
- the cooling device 47 is, for example, a heat exchanger which is supplied with energy from the same source as the pump stages 39, 40.
- the pre-cooling carried out in the cooling device 47 which is of course not necessary but is expedient for the method according to the invention, reduces the gas pressure and thus helps to avoid an increase in pressure in the container 45 which exceeds the maximum permitted operating pressure.
- Tanker truck 31 Tank supply line storage tank 11. - 32nd gas discharge storage tank
